Background: Sentinel node biopsy (SLNB) is the standard of care for breast cancer treatment and it is getting wide acceptance in Iran. The radiation safety of the procedure has been investigated under controlled conditions, but the standard dose of radiotracer and techniques are not always observed in the community setting. The aim of this study was to assess the magnitude of the absor...
Nodes in a mobile computing system are vulnerable to clone attacks due their mobility. In such attacks, an adversary accesses few network nodes, generates replication, then inserts this replication into the network, potentially resulting numerous internal attacks. Most existing techniques use central base station, which introduces several difficulties network's reliance on single point, while o...
background: this study evaluated the relation between telomere length in lymph node (ln) and prognosis of esophageal squamous cell carcinoma (escc). materials and methods: lns collected from 50 patients were assessed by pathological examination and quantitative reverse transcription polymerase chain reaction (qrt-pcr), which was used for detecting telomere length. the relation between clinical...
Introduction: Sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far.In the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer. Materials and Methods: Patients with biopsy-proven squamous cell carcinoma of the larynx were included...
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
